How To Determine If Stor Proc Parameter Is Output Or Input
Jul 23, 2005
I know that you can retrieve whether a parameter is for output buy way
of the "isoutparam" field, but is there anything that tells you whether
a parameter is input/output?
thanks
How I can get the best tutorial of using SQL Server 2005 Stored Procedured? For example this stor proc, -------------------------------------------------------------------------------- set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go
CREATE PROCEDURE [dbo].[COMPANY_ADD] -- Add the parameters for the stored procedure here @CompanyID INT, @CompanyName NVARCHAR(100), @CreatedDT Datetime AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; insert into COMPANY(CompanyID, CompanyName, CreatedDT, LastModifiedDT) values (@CompanyID, @CompanyParentID, @CompanyContactID, @CompanyName, @CreatedDT, @CreatedDT) return @CompanyID END -------------------------------------------------------------------------------------------------------------- I want to get tutorial of the meaning line by line? Thanks
I have a stored procedure which takes an input parm and is supposed to return an output parameter named NewRetVal. I have tested the proc from Query Analyzer and it works fine, however when I run the ASP code and do a quickwatch I see that the parm is being switched to an input parm instead of the output parm I have it defined as...any ideas why this is happening? The update portion works fine, it is the Delete proc that I am having the problems...

I am trying to create a stored proc that will take in a long string, but the stored proc does not allow me to take in more than 50 characters at a time. Is there a way to take away the limit? Please help me out, thanks in advance.
ALTER PROCEDURE dbo.TEST_TOTALCALLS ( @varDate as varchar (255), @StartDate as datetime, @EndDate as datetime ) AS
SELECT CASE @varDate WHEN 'Year' Then DATEPART(yy, CALLSTARTTIME) WHEN 'Quarter' Then DATENAME(qq, CALLSTARTTIME) WHEN 'Month' Then DATENAME(mm, CALLSTARTTIME) END, COUNT(*) as 'Total Calls' FROM CALLMASTER WHERE (COMMERCIALS = '1') AND (CALLSTARTTIME >= @StartDate) AND (CALLENDTIME <= @EndDate)
GROUP BY CASE @varDate WHEN 'Year' Then DATEPART(yy, CALLSTARTTIME) WHEN 'Quarter' Then DATENAME(qq, CALLSTARTTIME) WHEN 'Month' Then DATEPART(mm, CALLSTARTTIME), DATENAME(mm, CALLSTARTTIME) ' <---this part gave me an error, because of the comma, END ORDER BY CASE @varDate WHEN 'Year' Then DATEPART(yy, CALLSTARTTIME) WHEN 'Quarter' Then DATENAME(qq, CALLSTARTTIME) WHEN 'Month' Then DATEPART(mm, CALLSTARTTIME) END
The month case is giving me an error. I think it has to do with two expressions in one line. Anyone know how to combine that into 1 expression? or is there away to work around it? As I would like to display the month as Name, but group and sort by number. Thx!~
I have difficulty reading back the value of an output parameter that I use in a stored procedure. I searched through other posts and found that this is quite a common problem but couldn't find an answer to it. Maybe now there is a knowledgeable person who could help out many people with a good answer.The problem is that cmd.Parameters["@UserExists"].Value evaluates to null. If I call the stored procedure externally from the Server Management Studio Express everything works fine.Here is my code:using (SqlConnection cn = new SqlConnection(this.ConnectionString)) { SqlCommand cmd = new SqlCommand("mys_ExistsPersonWithUserName", cn); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add("@UserName", SqlDbType.VarChar).Value = userName; cmd.Parameters.Add("@UserExists", SqlDbType.Int); cmd.Parameters["@UserExists"].Direction = ParameterDirection.Output; cn.Open(); int x = (int)cmd.Parameters["@UserExists"].Value; cn.Close(); return (x>1); } And the corresponding stored procedure: ALTER PROCEDURE dbo.mys_Spieler_ExistsPersonWithUserName ( @UserName varchar(16), @UserExists int OUTPUT ) AS SET NOCOUNT ON SELECT @UserExists = count(*) FROM mys_Profiles WHERE UserName = @UserName
Hi Guys I am wondering if you could spare some time and help me out with this puzzle. I am new to this stuff so please take it easy on me.
I’m trying to create procedure which will take 2 input parameters and give me 1 back. Originally there will be more outputs but for this training exercise 1 should do. There are 2 tables as per diagram below and what I’m trying to do is Verify username & password and pull out user group_name.
For my proc. I am using some ideas from this and some other sites, but obviously i've done something wrong.
'==================================================== ALTER PROCEDURE dbo.try01 ( @UserName varchar(50), @Password varchar(50), @Group varchar Output ) AS SET NOCOUNT ON; SELECT TBL_USERS.USERNAME, TBL_USERS.PASSWORD,@Group = TBL_USER_GROUPS.GROUP_NAME, TBL_USERS.USER_ID, TBL_USER_GROUPS.GROUP_ID FROM TBL_USERS INNER JOIN TBL_USER_GROUPS ON TBL_USERS.GROUP_ID = TBL_USER_GROUPS.GROUP_ID WHERE (TBL_USERS.USERNAME = @UserName) AND (TBL_USERS.PASSWORD = @Password) '====================================================
and this is what i'm getting in VS.Net while trying to save.
'==================================================== ADO error: A select statement that assigns a value to variable must not be combined with data-retrieval operation. '====================================================
I did not see any samples on the net using ‘varchar’ as OUTPUT usually they where all ‘int’s. Could that be the problem?
I'm trying to call a stored procedure in an Execute SQL task which has several parameters. Four of the parameters are input from package variables. A fifth parameter is an output parameter and its result needs to be saved to a package variable.
Here is the entirety of the SQL in the SQLStatement property: EXEC log_ItemAdd @Destination = 'isMedicalClaim', @ImportJobId = ?, @Started = NULL, @Status = 1, @FileType = ?, @FileName = ?, @FilePath = ?, @Description = NULL, @ItemId = ? OUTPUT; I have also tried it like this: EXEC log_ItemAdd 'isMedicalClaim', ?, NULL, 1, ?, ?, ?, NULL, ? OUTPUT;
Here are my Parameter Mappings: Variable Name Direction Data Type Parameter Name User::ImportJobId Input LONG 0 User::FileType Input LONG 1 User::FileName Input LONG 2 User::FilePath Input LONG 3 User::ImportId Output LONG 4
When this task is run, I get the following error:
0xC002F210 at [Task Name], Execute SQL Task: Executing the query "EXEC log_ItemAdd @Destination = 'isMedicalClaim', @ImportJobId = ?, @Started = NULL, @Status = 1, @FileType = ?, @FileName = ?, @FilePath = ?, @Description = NULL, @ItemId = ? OUTPUT" failed with the following error: "An error occurred while extracting the result into a variable of type (DBTYPE_I4)". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. The User::ImportId package variable is scoped to the package and I've given it data types from Byte through Int64. It always fails with the same error. I've also tried adjusting the Data Type on the Parameter Mapping, but nothing seems to work. Any thoughts on what I might be doing wrong? Thanks.
How do I specify a parameter as an output parameter --> OUTPUT paramI am referring to how to do this on line 10 below 1 int GetTheReturnValue=0;2//Code not shown// 9 mySqlCommand.Parameters.Add("@returnParameter", SqlDbType.Int, 10).Value = 0; // How to specify output param?10 GetTheReturnValue=mySqlCommand.ExecuteNonQuery();
in a asp .net application, I call a stored procedure which have a output parameter. the output parameter works find in sql session, but not in the asp .net application.
if I put select msg_out = "error message" in position A(see below for stored proc), it works fine if I put them inside the if statement, the output parameter wont work in asp .net application, but fine in SQL session The stored proc was created like this:
Create procedure XXXXXXX (@msg_out varchar(80) OUTPUT ) as begin
while exists (*******) begin //position A if certain condition begin
select msg_out = "error message" return 1 end
end
end
end
It seems to me that anything inside if - the second begin...end - it wont get executed.
I have a stored procedure that returns a resultset AND an output parameter, pseudocode:myspGetPoll@pollID int,@totalvoters int outputselect questionID,question from [myPoll] where pollID=@pollID @totalvoters=(select count(usercode) from [myPoll] where pollID=@pollID)1. In my code behind I'd like to read both the rows (questionID and question) as well as total results (totalvoters) How could I do so?2. what would be the signature of my function so that I can retreive BOTH a resultset AND a single value?e.g.: private function getPollResults(byval pollID as integer, byref totalvoters as integer) as datasetwhile reader.read dataset.addrow <read from result>end whiletotalvoters=<read from result>end functionThanks!
Using Sql Srv 7I know I can use the system sp's sp_stored_procedures and sp_sproc_columnsto determine all the sps in a db, and what input parms there are for aparticular sp... but... if the sp returns a result set, is there a way tofind out the stru of that in a similar manner???
I have a problem with SP when passing in Parameters. Basically something like this:
-- Pass 1, 2 or 3 as parameter EXEC SP_mySP 1
-- The SP will do the following SQL Statement SELECT * FROM myTable WHERE ( (If @Parameter1 = 1 then myColumn = 'A' or myColumn = 'B') (If @Parameter1 = 2 then myColumn = 'C') (If @Parameter1 = 3 then myColumn is not null) )
I am trying to get a stored proceedure to return the autogenerated numerical primary key of the last row created to our appliciation. I have created what I thought was an output parameter to handle this however when the application runs I get a message that seems to indicate that it is ASKING for the parameter instead of returning it. Here is the code of the sproc:
Code Block USE [chronicle] GO /****** Object: StoredProcedure [dbo].[CreateNewLicense] Script Date: 01/03/2008 06:35:52 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[CreateNewLicense]
After running my ssis pkg for some time with no problems I saw the following error come up, probably during execution of a stored procedure ...
An OLE DB error has occurred. Error code: 0x80040E14. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E14 Description: "The formal parameter "@ReportingId" was not declared as an OUTPUT parameter, but the actual parameter passed in requested output.".
I see some references to this on the web (even this one) but so far they seem like deadends. Doe anybody know what this means? Below is a summary of how the variable is used in the stored proc.
The sp is declared with 21 input params only, none of them is @ReportingId. It declares @ReportingId as a bigint variable and uses it in the beginning of the proc as follows...
Code Snippet select @ReportingId = max(ReportingId) from [dbo].[GuidToReportingid] where Guid = @UniqueIdentifier and EffectiveEndDate is null
if @ReportingId is null BEGIN insert into [dbo].[GuidToReportingId] select @UniqueIdentifier,getdate(),null,getdate() set @ReportingId = scope_identity() END ELSE BEGIN select @rowcount = count(*) from [dbo].[someTable] where ReportingId = @ReportingId and...lots of other conditions
...later as part of an else it does the following...
Code Snippet if @rowcount > 0 and @joinsMatch = 1 begin set @insertFlag = 0 end else begin update [dbo].[GuidToReportingId] set EffectiveEndDate = getdate() where ReportingId = @ReportingId insert into [dbo].[GuidToReportingId] select @UniqueIdentifier,getdate(),null,getdate() set @ReportingId = scope_identity() end
...and before the return it's value is inserted to different tables.
I'm trying to use the Merge component. When i attach a datasource to the the component, the Select Input/Output dialog box should popup.. It does, but VS.NET is hanging and i can only shutdown the procesess...
Any idea how i should solve this? how can i re-register this component?
The foolowing code I cannot seem to get working right. There is an open connection c0 and a SqlCommand k0 persisting in class.The data in r0 is correct and gets the input arguments at r0=k0->ExecuteReader(), but nothing I do seems to get the output values. What am I missing about this?
The variable 1 is created as int32 and variable 2 is created as dattime.
When i execute the SQLtask, I get error:
[Execute SQL Task] Error: Executing the query "Exec mysp 'table1',OUTPUT,OUTPUT" failed with the following error: "Error converting data type nvarchar to int.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
What am i missing. I tried changing the data types adding the input variable also as a variable in the mapping. Nothing seems to work. Any ideas please?
I need to loop the recordset returned from a ExecuteSQL task and transform each row using a Data Conversion task (or a Script Task).
I know how to loop the recordset returned by an ExecuteSQL task:
http://www.sqlis.com/59.aspx
I loop the returned recordset (which is mapped to a User variable of type System.Object) and assign the Variable Mappings in the ForEach Loop to different user variables which map to the Exec proc resultset (with names and data types).
I assume to now use these as the Available Input columns for the Data Conversion task, I drag a Data Flow task inside the For Each Loop container and double-click it, then add a Data Conversion task.
But the Input columns (which I entered in the Variable Mappings in the ForEach Loop containers) dont show up in the Available Input columns of the Data Conversion task.
How do I link the Variable Mappings in the ForEach Loop containers from the recordset returned by the Execute SQL Task to the Available Input columns of the Data Conversion task?
.......................
If this is not possible, and the advice is to use the OLEDB data flow as the input for the Data Conversion task (which is something I tried too), then the results from an OLEDB Command (using EXEC sp_myproc) are not mapped to the Available Input columns of the Data Conversion task either (as its not an explicit SQL Statement and the runtime results from a stored proc exection)
I would like to use the ExecuteSQL task to do this as the Package is clean and comprehensible. Which is the easiest best way to map the returned results from a Stored proc execution to the Available Input columns of any Data Flow transformation task for the transform operations I need to execute on each row of data?
[ Could not find any useful advice on this anywhere ]
I created a package that seems to work fine with a small amount of data. When I run the package however with more data (as in production) the merge join output is limites to 9963 rows, no matter if I change the number of input rows.
Situation as follows.
The package has 2 OLE DB Sources, in which SQL-statements have been defined in order to retrieve the data.
The flow of source 1 is: retrieving source data -> trimming (non-key) columns -> sorting on the key-columns.
The flow of source 2 is: retrieving source data -> deriving 2 new columns -> aggregating the data to the level of source 1 -> sorting on the key columns.
Then both flows are merged and other steps are performed.
If I test with just a couple of rows it works fine. But when I change the where-clause in the data source retrieval, so that the number of rows is for instance 15000 or 150000 the number of rows after the merge join is 9963.
When I run the package in debug-mode the step is colored green, nevertheless an error is displayed:
Error: 0xC0047022 at Data Flow Task, DTS.Pipeline: SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "Merge Join" (4703) failed with error code 0xC0047020. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure.
To be honest, a few more errormessages appear, but they don't seem related to this issue. The package stops running after some 6000 rows have been written to the destination.
I'm trying to create a fairly simple custom transform component (because I've read that's the easiest one to create) which will take one column from a flat file source and based on the first row create the output columns. I'm actually trying to write a component that will solve the now well known problem with parsing CSV files in SSIS. I have a lot of source files and all have many columns so a component that can read in the first line from the CSV file and create the output columns automatically will save me lots of time when migrating the old DTS packages.
I have the basic component set up but I'm stuck when trying to override the OnInputPathAttached method because I don't know how to use the inputID to get the first line from the input (the buffer). Are there any good examples for creating output columns dynamically based on the input buffer? Should I just give up on on the transform and create a custom source component instead?
How can I view the output of a stored procedure that is returning a OUTPUT variable? I've written a stored proc that uses OUTPUT but when I run it, all I see is "The command(s) completed successfully." I'm at a loss on how to debug/verify/view the output value.
The same thing happens using this example from MS.
CREATE PROCEDURE titles_sum @TITLE varchar(40) = '%', @SUM money OUTPUT AS SELECT 'Title Name' = title FROM titles WHERE title LIKE @TITLE SELECT @SUM = SUM(price) FROM titles WHERE title LIKE @TITLE GO
Hi, I need to do the following task, which is described by pseudo-code SELECT * FROM Customers SORT BY @SortExpression How can I do something like it (sorting according to input parameter) Thanks for any idea
Hi everyone, I have a question that I believe should be simple to answer yet I cannot find the answer anywhere. I am trying to make it possible for my report to clear the input box whenever the report is run or when anything in a dropdown list is selected. The reason why I want this is because my report has a dropdown list that inputs date ranges for "quick" report info. The other option is to manually type in the begin and end date. If anyone could help me out with this I would be very grateful.
I haven't been able to successfully use the ADO.NET connection type to use both input and output parameters in an execute sql task containing just tsql statements (no stored procedure calls). I have successfully used input parameters on their own but when i combine it with output parameters it fails on the simplest of tasks.
I would really find it beneficial if you could use the flexibility of an ADO.NET connection type as the parameter marker and parameter name can be referenced anywhere throughout the sql statement in no particular order. The addition of an output parameter would really make it great!!
Has anyone ever tried to use a cursor as an output variable to a stored proc ?
I have the following stored proc - CREATE PROCEDURE dbo.myStoredProc @parentId integer, @outputCursor CURSOR VARYING OUTPUT AS BEGIN TRAN T1 DECLARE parent_cursor CURSOR STATIC FOR SELECT parentTable.childId, parentTable. parentValue FROM parentTable WHERE parentTable.parentId = @parentId OPEN parent_cursor
SET @outputCursor = parent_cursor
DECLARE @childId int DECLARE @parentValue varchar(50) FETCH NEXT FROM parent_cursor INTO @childId, @parentValue WHILE @@FETCH_STATUS = 0 BEGIN SELECT childTable.childValue FROM childTable WHERE childTable.childId = @childId
FETCH NEXT FROM parent_cursor INTO @childId, @parentValue END
CLOSE parent_cursor DEALLOCATE parent_cursor COMMIT TRAN T1 GOAnd, I found that I had to use a cursor as an output variable because, although the stored proc returns a separate result set for each returned row in the first SQL statement, it did not return the result set for the first SQL statement itself.
My real problem at the moment though is that I can't figure a way to get at this output variable with VB.NET.Dim da as New SqlDataAdapter() da.SelectCommand = New SqlCommand("myStoredProc", conn) da.SelectCommand.CommandType = CommandType.StoredProcedure Dim paramParentId as SqlParameter = da.SelectCommand.Parameters.Add("@parentId", SqlDbType.Int) paramParentId.Value = 1
Dim paramCursor as SqlParameter = daThread.SelectCommand.Parameters.Add("@outputCursor") paramCursor.Direction = ParameterDirection.OutputThere is no SqlDataType for cursor. I tried without specifying a data type but it didn't work. Any ideas?
